bootknocking 

The definative definition of Boot knocking is simply a Ghetto term for getting some, or actually having sex with someone.

Example: "Yo, playa me and my girl did some serious bootknocking all night long."

Or the line in a song that goes;

"Good love body rocking knocking boots all night long, ha haaaa. Making love to ya till the break of dawnnnn, oh come on...."
